`ivPRovrwnsNT IN GRAIN-BINDERS.

vSpecification forming part of Letters Patent No. 156,301, dated October 27,1874; application filed A f f June 13,1874.

To all 'whom it mayA concern l Be it known that LI, J AMES: MCNEAL', 4of Chauncey,in` the, county of Lawrence and State of Illinois, have invented afnew and Improved Grain-Binder, of which the following is aspecification: Y

Myinvention consists of a pair of gripingl arms, in combination with a sewing-machine needle and shuttle and looping-hooks, so contrived that they gripe the gavel, compress it, and pass it across the needle-hole into a bight ofthe twine, and hold it while the twine is being tied by the sewing-machine devices, all in a manner calculated to make a simple but efflcient machine.

Figure l is a front elevation of the upper part of the machine, and aqsection of the table or platform. Fig. 2 is' a sectional elevation taken at right anglesv t the plane of Fig. 1. Fig. 3 is a partial front elevation of the ma chine, showing the position of the gripers while holding the gavel for the tying of the band. Fig. 4 is a horizontal section taken on the line .r of Fig. 2;" Fig is a plan of the under side of the plate or table, showing the arrangement of the llooping-hooks and the shuttle. f

Similar letters of reference indicate correspending parts.

A is the platform or table, on which the gavel is received from the reaping-machine to be bound. B and C fare griping arms or jaws, for compressing the gavel,"carrying it across the line of the needle," against the twine, and into a bight of it, and holding the gavel while the band is being tied. These arms are piv-V otcd at the upper end to a vertically-moving plate, D, arranged in guideways in a head, E, and connected, by an angular slot, F, with a crank-pin, G, of a disk, H, on a short shaft, I, in the upper part of the head, which is geared y by the wheel J and pinion K with the crankshaft L, which drives another vertically-reciprocating plate, M, by a crank-pin,N, in its disk O, which connects with said slide by a V-shaped slot, P, in it. The griping-arm B is held stationary to receive the gavel against it; but it is adjustable toward and from the needle, to adapt it for large or small bundles; and it is held in position by a spring-pawl, Q, and rack'B. The arm G is connected, near its lower end, to a bar, S, which is pivoted to the head at T, so that when the plate D rises it will swing the arm upward, to allow the gavel tobe delivered under it ontothe table, Where the arm will catch itwhen the plate moves down, and push it under the needle and against the arm B.

After the gavel is thus received and secured in the griping-arms, the needle U goes down with the twine, and-the hooks V catch the loop and hold it open in a kind of horizontal loop, that is accomplished by means of the stud attached to the ring X and different-sized cam-slots in the extensions of the hook. As the ring is forced around, the hook with the smallest transverse play in the s lot seizes the twine and delivers it to the next succeeding hook, which latter, as it is operated upon by its stud in the slot, receives the same and passes it to the next, until a perfect horizontal loop is formed. After the loop is thus formed the needle descends a second time and passes through the said loop, and the shuttle W goes between the needle and the thread below the first loop held on the hooks, and locks the needle-thread; then the hooks throw oif their loop, and the needle-thread draws up and forms a knot above the plate. then let go, and allow the sheaf to expand in the band against the knot, and make the band tight. Then, while the next gavel is gathering, another knot is tied to connect the twine, and the twine is cut between the two knots, for freeing 'thesheaf to be discharged either -by hand or any convenient mechanism. The

needle-shaft makes two motions to one of the griping-arms by means of the gears, and the needle makes two movements to one of the shaft by means of the slot P, in order to deliver the thread to the hooks, and then go through the loop held open by them, while the gripers hold the gavel.

Y VThe hooks are attached to a ring or wheel, X, arranged in a recess in the under side of the table above the shuttle, and they are turned to catch the loop and spread it out by the catch y on the shuttle-working bar Z, which strikes the stud-pin a on the wheel just before the bar comes to rest, when the shuttle is moved back to the left; (see Fig. 5;) and they are moved back again, ready for the next op- The griping-arms eration when the shuttle goes to the other end of its movement, by thefcatch b coming against the same stud. v I Y The needle also makes two movements to one of the shuttle by the V slot, so that the hooks take the twine at one movement, and the shuttle takes it at the next.

The shuttle-driver is worked by the swinglever d, which is connected to the crank e on the driving-pulley g by the connecting-rod f;

but a vertical shaf gearing with the drivingshaft, and having a crank on the lower'end, connected with the shuttle driver, may be used, if preferred.

When the shuttle goes through the loop below the hooks, the hooks move together a little by the tension of the twine, and thus lessen the friction of the loop on the shuttle, the hook being at that time free from the catch which swings them out.

The knot tied by the machine is of the kind known as a weavers knot. p

The griping-arms may be used with other sewing-machine devices for tying the knot, if preferred.

The rod j prevents the gavel from vbeing forced up between the arms. Y

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1 1. In a grain-binder, ,the combination of griping-arms B and C, the former held vertical, or nearly so, and both pivoted to a vertically-reciprocating plate, D, and the bar S, pivoted to a fixed support, substantially as shown and described.

2. Thecombination of griping-arms B and C, connecting-bar S, sliding plate D, needle U, hooks V and y, ring X, and the shuttle, as

shown and described, .to operate as specied.

3. The arms B and G, spring-pawl O, and

vtoothed bar R, combined and arranged substantially as speciiied.

4. The combination of hooks V, needle U, ring or wheel X, shuttle W, and shuttledriver Z, as shown and described.

`5, The Acombination of needle U, disk O, shaft L, pulley g, rod f, lever d, shuttle and shuttlcdriver, pivoted hooks V, ring X, hook y, as shown and described.
